Method of compensating colors in image display device for users with color vision deficiency and device of the same

Abstract

Disclosed are a method of compensating colors in an image display device for users with color vision deficiency and a device of the same, enabling the users with color vision deficiency to view display images as vividly and naturally as normal users. The method for compensating colors in an image display device includes a step of determining whether a user is partially color blind or normal, and a step of controlling gain values of a plurality of color signals depending upon the user's color perceptivity so as to compensate colors displayed on a screen, if the user is determined to be partially color blind.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of Korean Application No. P2003-078675, filed on Nov. 7, 2003, which is hereby incorporated by reference as if fully set forth herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to an image display device, and more particularly, to a method of compensating colors in an image display device for users with color vision deficiency and a device of the same. Although the present invention is suitable for a wide scope of applications, it is particularly suitable for allowing users with deficient color vision, namely, partial color blindness, to view displayed images as vividly and naturally as normal users. [0004] 2. Discussion of the Related Art [0005] Recently, technologies of image display devices have shown remarkable improvement, more specifically, in that the displayed colors are represented as vividly and elaborately as natural colors. And, such ...

AI Technical Summary

Benefits of technology

The present invention provides a method and device for compensating colors in an image display device for users with color vision deficiency. The method includes determining if a user is partially color blind or normal and controlling gain values of a plurality of color signals accordingly. The device includes a memory for storing test patterns and user information, and a controller for determining the user's partial color blindness and color perceptivity based on the test patterns or user information and controlling the gain values of the color signals accordingly. The device also displays an icon or message to indicate that the colors of the screen are being compensated. The technical effects of the invention include allowing partially color blind users to view the displayed image through the same color vision as that of normal users and improving the overall visual experience of users with color vision deficiency.

Problems solved by technology

However, users with color vision deficiency (i.e., color blindness or partial color blindness), who do not have the same vision characteristics for colors as normal people, may view the colors displayed from the image display device differently as compared to normal users.

However, the partially color blind individuals lack perceptivity for certain colors only and are fully capable of distinguishing the rest of the colors.

Therefore, in certain cases, the partially color blind people are completely unaware of their color deficient vision, which leads them to the misconception that the colors seen through their eyes are in fact natural and normal to everybody else.
